Well, for starters M-Prove "has treated over 100 million tons of coal without any reported issues" already so if CCTC had anything to do with it they would have something called...hmm what is it again? ...that line on their balance sheet that is always $0... oh yeah REVENUES...

But more importantly if you look at M-Prove's website you can see that their process is completely different than that which CCTC describes as the Pristine M process...

"Our patented M-Prove™ Additives was developed to provide the benefits of halogen for mercury control, without the negative impacts. We use a form of halogen that can be applied at very low levels. This essentially eliminates the risk associated with halogen injection while achieving similar mercury control benefits."

Halogens are group 7A on your periodic table and can be dangerous for humans to work with in certain forms...Things like chlorine gas are fatal, but other substances with Cl(chlorine) like NaCl or table salt are not. This process of M-Prove is a way to inject halogens into coal without the dangerous effects it can have on the human body or the corrosive effects it can have on equipment.

Halogens are most noted in chemistry for their oxidation properties:

Probably the most important generalization that can be made about the halogen elements is that they are all oxidizing agents; i.e., they raise the oxidation state, or oxidation number, of other elements—a property that used to be equated with combination with oxygen but that is now interpreted in terms of transfer of electrons from one atom to another. In oxidizing another element, a halogen is itself reduced; i.e., the oxidation number 0 of the free element is reduced to -1. The halogens can combine with other elements to form compounds known as halides—namely, fluorides, chlorides, bromides, iodides, and astatides. Many of the halides may be considered to be salts of the respective hydrogen halides, which are colourless gases at room temperature and atmospheric pressure and (except for hydrogen fluoride) form strong acids in aqueous solution. Indeed, the general term salt is derived from rock salt, or table salt (sodium chloride). The tendency of the halogen elements to form saltlike (i.e., highly ionic) compounds increases in the following order: astatine < iodine < bromine < chlorine < fluorine. Fluorides are usually more stable than the corresponding chlorides, bromides, or iodides. (Often astatine is omitted from general discussions of the halogens because less is known about it than about the other elements.)

Some good articles on this process of Mercury and Halogen reactions:

Here is a youtube video that shows a halogen and mercury oxidation reaction and the result precipitate formed that now can be collected and reduce a facility's mercury emissions
